Am I Your Type??
You don't have to be a warrior to know the largest volcanoes have this shape.
What is a shield?
85% of the world's volcanoes are found here.
What is the Pacific ring of fire?
Lava is easier to study than magma for this reason.
What is it is on the surface of the Earth?
You can easily outrun this volcanic hazard.
What is a lava flow?
Volcanoes are classified as dormant when they are this?
What is in between eruptive phases?
If you have subduction, then you will always find this type of volcano.
What is a composite volcano?
Volcanoes far from plate boundaries are found over this feature in the mantle.
What are hot spots?
If your silica content is low, we would call you this type of magma.
What is mafic magma?
This volcanic hazard is fast moving, really dense, and can come roaring down a composite volcano months after it has erupted.
What is a lahar?
What kind of rock is formed when lava cools and hardens?
What is igneous rock
Steep sided volcanoes composed only of small pyroclastics are called this
What is a Cinder Cone volcano
The Great Rift Valley of Africa has lots of volcanic activity because the crust is doing this.
What is diverging?
This compound is the big factor in determining magma behavior.
What is Silica?
These deadly hazards are very hot, very fast, and full of debris and gases.
What are pyroclastic flows?
A caldera is created when this happens?
What is the magma chamber empties and the volcano collapses?
They are called composite volcanoes for this reason.
What is they are a "composition" of many layers of ash/pyroclastics and lava flows?
Almost all of the explosive, dangerous volcanoes on Earth are found by this plate tectonic feature.
What are subduction zones?
How would you describe felsic magma's viscosity?
What is high viscosity? (thick, sticky, explosive too!)
If enough of this volcanic gas gets ejected into the atmosphere, it can block the suns energy and lower the temperature of Earth.
What is a sulfur dioxide?
Eruptions of very thin mafic lava that last thousand or millions of years covering thousands of acres are called this.
What are flood basalts?
Rift zones usually produce this type of volcano due to the low viscosity of the magma.
What is a shield volcano.
13% of the world's volcanoes are found in this region.
What is the Mediterranean belt?
High silica content magma can be VERY explosive for this reason.
What is it's ability to trap gases and build massive pressure?
If a volcanic mountain that is unstable is perched above the ocean, it has the potential to unleash this deadly phenomenon.
What is a mega tsunami?
The melting point of magma is mainly determined by these three things?
What is pressure, silica content and presence of water?
